Doesn’t cache multilanguage page on different domain

Hi
I installed and configured Swift plugin but there is an issue with caching second language pages which are on the different domain.

on https://suknieboho.pl – the caching works fine and fast (except browser caching which doesn’t work). I have second language installed on different domain https://thebohodresses.com (using WPML plugin) and swift doesn’t cache those pages on this domain at all.

could you verify this issues?

regards
Kuba
